PowerPC floating point little-endian [5 of 15]

[Alan Modra]

Rid ourselves of ieee854.

	2013-07-10  Alan Modra <amodra@gmail.com>

	* sysdeps/ieee754/ldbl-128ibm/ieee754.h (union ieee854_long_double):
	Delete.
	(IEEE854_LONG_DOUBLE_BIAS): Delete.
	* sysdeps/ieee754/ldbl-128ibm/math_ldbl.h: Don't include ieee854
	version of math_ldbl.h.
	(ieee854_long_double, ieee854_long_double_shape_type): Define.
